The proven, tested and trusted acme rod system has been used for hundreds of years. We took the acme height adjustment concept and made it fit the Vyper Chair.

With this height adjustment, you can quickly & easily adjust the height of your chair by simply spinning the seat to go up & down.

**The Acme Rod Attachment can replace the Quick Height Adjustment.
**The Acme Rod Attachment cannot be used on Lay-Down Creeper, Low-Pro or Robust Steel Pro.

★★★★★ - Anthony N.

The Vyper chair is everything I expected. The build, strength and comfort. The delivery was quick and the setup and assembly was simple. This is a heavy duty chair that I will never replace

★★★★★ - James B.

I am the envy of everyone in my shop. The chair is awesome. Exactly what I wanted. Sturdy, rolls smoothly and no concern of tipping. Couldn’t be happier

★★★★★ -Daniel T.

amazing chair. Its comfortable for hours of welding and fabricating. My old chair killed me after a few hours in it. I can go all day in the elevated steel max.
